-# Migration guide
-
-This repository will be renamed from **asn-ip** to **as-ip-blocks**.
-
-## Migration steps
-
-1. If only consuming plaintext files: just update the download URL, no code changes needed
-2. Update repository URLs in your code from `ipverse/asn-ip` to `ipverse/as-ip-blocks`
-3. If parsing JSON: handle the `metadata` nested object and `subnets` → `prefixes` rename
-
-## What's changing
-
-### Repository name
-- Old: `ipverse/asn-ip`
-- New: `ipverse/as-ip-blocks`
-
-### File structure
-
-The file structure remains the same:
-```
-as/1/aggregated.json
-as/1/ipv4-aggregated.txt
-as/1/ipv6-aggregated.txt
-```
-
-### JSON format
-
-**Old:**
-```json
-{
-  "asn": 1,
-  "handle": "LVLT-1",
-  "description": "Level 3 Parent LLC",
-  "subnets": {
-    "ipv4": [
-      "177.75.88.0/24",
-      "177.75.90.0/24"
-    ],
-    "ipv6": []
-  }
-}
-```
-
-**New:**
-```json
-{
-  "asn": 1,
-  "metadata": {
-    "handle": "LVLT-1",
-    "description": "Level 3 Parent LLC",
-    "countryCode": "US",
-    "country": "United States",
-    "origin": "authoritative"
-  },
-  "prefixes": {
-    "ipv4": [
-      "177.75.88.0/24",
-      "177.75.90.0/24"
-    ],
-    "ipv6": []
-  }
-}
-```
-
-**Changes:**
-- `subnets` renamed to `prefixes`
-- `handle`, `description` now nested under `metadata` object
-- Added `countryCode` field in metadata (ISO 3166-1 alpha-2 code or `null`)
-- Added `country` field in metadata (country name in English or `null`)
-- Added `origin` field in metadata (values: `authoritative`, `inferred`, `overlaid`, `none`)
-
-### Plaintext format
-
-The plaintext format remains the same with separate IPv4 and IPv6 files:
-
-ipv4-aggregated.txt:
-```
-# AS1 (LVLT-1)
-# Level 3 Parent LLC
-#
-177.75.88.0/24
-177.75.90.0/24
-```
-
-ipv6-aggregated.txt:
-```
-# AS1 (LVLT-1)
-# Level 3 Parent LLC
-#
-2a01:1234::/32
-```
